428 Horne and Williamson.—The Morphology and 
These two new species show certain resemblances to Verticillium in 
form and arrangement of conidiophores, whilst E. catemdata sometimes pro¬ 
duces a typical Penicillium form of conidiophore. They are separated from 
Verticillium and Penicillium by their possession of a second type of spore 
which is a constant feature in both of them. 
The genus Papidaspora, originated by Preuss ( 16 ), includes many forms 
with bulbils which have been named without reference to the existence of 
any other form of reproduction ; for example, Papidaspora magnificus , 
Hotson (8), was found to be an asexual stage of Ascobolus magnificus , and 
Dodge ( 5 ) has shown that sexual reproduction occurs in cultures containing 
two strains properly chosen. As the genus at present stands there are at 
least nine species of Papidaspora as yet unconnected with any perfect form. 
Moreau suggests that the nomenclature proposed by Lindau should be 
adopted and all fungi with bulbils of the type of Papidaspora aspcrgilli- 
formis should be classed as Eidamia . Papidaspora aspergilliformis is 
synonymous with E. acremonioides. 
The case of Hclicosporangium parasiticum is also of interest in this con¬ 
nexion. A fungus was described and given this name in 1865 by Karsten 
( 10 ). In 1883 Eidam (6) described a form which he called by the same name, 
but it is very probable that the Hclicosporangium of Karsten and the Hcli¬ 
cosporangium of Eidam are not the same fungus. Eidam describes his fungus 
as possessing bulbils exactly like those of Eidamia acremonioides . He 
further figures the sterigma as a single-celled flask-shaped body borne singly 
on a hypha or in groups on a conidiophore. The figures of these conidio¬ 
phores are markedly like those represented in Fig. 3 for E. acremonioides. 
Eidam does not mention the formation of any f chlamydospores ’. Bainier ( 1 ) 
objects to the separation of Hclicosporangium parasiticum from Papidaspora 
aspergilliformis (E. acremonioides) on the ground that it is a ‘ monstrous 
form * that the Mucedineae often present. With the facts in mind of the 
variation presented by E. acremonioides when grown on different media, the 
writers are inclined to agree with Bainier and to regard Hclicosporangium 
parasiticum as probably synonymous with Eidamia acremonioides. Possibly 
in the case of H. parasiticum the macrospore was overlooked or was absent 
from the particular medium on which the fungus was growing. 
Large brown spores were found on seeds of Fcstuca pratensis by 
A. L. Smith ( 19 ). These were borne singly on the ends of branches on 
a colourless mycelium and were named Langloisula macrospora by Smith 
on account of their resemblance to Langloisula spinosa , Ellis and Everhart. 
Smith suggested that this genus rests on too narrow a foundation and 
should be included with Acremoniclla . Later Pethybridge ( 15 ) cultured 
the same fungus from brown spores occurring on blighted potato foliage. 
He noted the peculiar branching, recalling that of Monopodium , and sent 
the specimen to Paris for comparison with M. uredopsis , Delacroix (4).
